Once I was at Phoenix Zoo(about 3nm from Sky Harbour airport, for a jet, its about 1 minute to landing) and saw a dash 8 (America West Express or US airways Express)approaching gear up, and didn't see it put the gear down. The gear was still up when it disappeared behind the trees, I guess he put it down at the last minute(or should I say seconds?)

"There are two types of pilots, those that have landed gear up, and those that will"
(hope its not too true)
